Peer Victimization in Youth with Tourette’s Syndrome and Chronic Tic Disorder: Relations with Tic Severity and Internalizing Symptoms

The present study analyzed rates of peer victimization in children with a chronic tic disorder as compared to children with type 1 diabetes and healthy controls. The associations among peer victimization, tic symptom severity, and psychological symptoms, as well as the potential mediating relationship between peer victimization, tic severity, and child internalizing symptoms, were also explored. Children with tics displayed higher rates of peer victimization than control groups, and peer victimization in children with tics was positively correlated with tic symptom severity, loneliness, anxiety symptoms, and parent report of child internalizing symptoms. Results also supported the hypothesis that peer victimization mediates the relationship between tic symptom severity and loneliness. Findings highlight the importance of the assessment and treatment of psychosocial variables in children with chronic tic disorders, including social functioning and peer relationships.     

Categorical Abstract Algebraic Logic: Prealgebraicity and Protoalgebraicity

Two classes of π are studied whose properties are similar to those of the protoalgebraic deductive systems of Blok and Pigozzi. The first is the class of N-protoalgebraic π-institutions and the second is the wider class of N-prealgebraic π-institutions. Several characterizations are provided. For instance, N-prealgebraic π-institutions are exactly those π-institutions that satisfy monotonicity of the N-Leibniz operator on theory systems and N-protoalgebraic π-institutions those that satisfy monotonicity of the N-Leibniz operator on theory families. Analogs of the correspondence property of Blok and Pigozzi for π-institutions are also introduced and their connections with preand protoalgebraicity are explored. Finally, relations of these two classes with the (, N)-algebraic systems, introduced previously by the author as an analog of the -algebras of Font and Jansana, and with an analog of the Suszko operator of Czelakowski for π-institutions are also investigated.

How to turn a hawk into a dove and vice versa: Interactions between emotions and goals in a give-some dilemma game

The present study investigated emotional influences on behavior in a one-shot, simultaneous, give-some dilemma game. In accordance with functional perspectives on the role of discrete emotions, we found fear to reduce, and guilt to increase levels of cooperation. Moreover, we showed individual differences in the effect of induced emotional states. Specifically, results indicated that inducing fear reduced cooperation only for individuals with a pro-social value orientation, and that guilt induction increased cooperation only for individuals with a pro-self value orientation. We also established that both social value orientations could be adequately described in terms of differences in chronically accessible goals (as assessed by value-importance ratings). These results, therefore, seem to support our hypothesis that individual differences in the behavioral consequences of induced emotional states are related to variation in chronic accessibility of general goals associated with a particular emotional state.     

Apprendre à résoudre des problèmes en favorisant la construction d’une représentation alternative chez des élèves scolarisés en éducation prioritaire

In arithmetic problems solving, the representation of the problem spontaneously induced by the content of the statement is not always compatible with the solving strategy. This study evaluates a learning approach designed to lead pupils to build an alternative representation to the one spontaneously induced. In this paper, we evaluate the efficiency of this learning approach with children with learning difficulties enrolled in a priority education network. This learning by semantic recoding is a process based on an analogy between the problems and a comparison of strategies. The results show that after learning, the pupils built alternative representations.     

Something from nothing: exploring dimensions of children's knowing through the repeated reading of favourite books

Witte‐Townsend and DiGiulio explore some of the dimensions of knowing that children, teachers and parents may engage together during story‐time. They reflect on some of their own long‐term relationships with children and children's books, especially Phoebe Gilman's Gilman P 1992 Something from nothing (New York, NY, Scholastic Inc)  [Google Scholar] Something from nothing (published in 1992) and Simms Taback's Taback S 1999 Joseph had a little overcoat (New York, NY, Viking‐Penguin)  [Google Scholar] Joseph had a little overcoat, published in 1999. The authors probe issues such as why children ask to hear a favourite story over and over and why they suddenly abandon all interest and move on to a new book. They explore the meaning of the silences that sometimes arise during story‐time, pooling around the young listeners as the last words of the book are read. Witte‐Townsend and DiGiulio remind us of the value of literature in the lives of children and they affirm that the reading and re‐reading of favourite stories enables the understanding of complex human issues and contributes significantly to social, emotional and spiritual growth.     

帕金森病诊断标记物系统回顾与展望

本篇综述总结了帕金森病的诊断、鉴别诊断和病程监测的各领域的生物学标记物的研究进展。其中重点介绍了神经影像学和生物化学领域的生物学标记物,也是当前研究较为成熟的两大领域。神经影像学标记物以多巴胺能影像及非多巴胺能影像为代表,生物化学标记物为包括a一突触核蛋白在内的多种蛋白和激素,两者的结合能够有效提高疾病诊断的特异性和灵敏性。同时文章还介绍了当前研究的热点——帕金森病的前驱诊断手段,即在疾病典型的运动症状和非运动症状出现前便可预测帕金森病的诊断手段。     

19世纪帕金森病的研究历史

1817年Parkinson首先描述了震颤麻痹,此后的45年中陆续出现了一些相关报道,但并未增加有价值的临床信息。1861年以后,Charcot对此病进行了深入的研究,认识到动作缓慢是本病的核心症状之一,并将其与肌强直鉴别开。他细致地描述了面具脸等症状,认为震颤并非诊断的必要因素,在命名上建议用帕金森病来取代震颤麻痹。     

Modeling and estimating recall processing capacity: Sensitivity and diagnostic utility in application to mild cognitive impairment

We investigate the potential for using latency-based measures of retrieval processing capacity to assess changes in performance specific to individuals with mild cognitive impairment (MCI), a reliable precursor state to Alzheimer’s Disease. Use of these capacity measures is motivated in part by exploration of the effects of atrophy on a computational model of a basic hippocampal circuit. We use this model to suggest that capacity may be a more sensitive indicator of the underlying atrophy than speed of processing, and test this hypothesis by adapting a standard behavioral measure of memory (the free and cued selective reminding test, FCSRT) to allow for the collection of cued recall latencies. Participants were drawn from five groups: college-aged, middle-aged, healthy elderly, those with a diagnosis of MCI, and a sample of MCI control participants. The measure of capacity is shown to offer increased classificatory sensitivity relative to the standard behavioral measures, and is also shown to be the behavioral measure that correlated most strongly with hippocampal volume.     

百年郑玄易学研究的回顾与反思

1905至2010年间的郑玄易学研究经历了三个阶段,其中既有对传统经学研究路数的坚守,又有引入西学思想与方法的新实践,而现代学术制度、思想与方法最终成为郑易研究的主导,呈现出新旧学术交替的丰富性与复杂性,是中国传统学术现代化的缩影。西方学术的引入,客观上丰富了郑易研究的视角与途径,揭示、提升了郑易研究的多方面内容,其百年历程及特点也都显示出这一研究的新气象、新变化。然而,脱离传统经学理路的郑易研究,也存在着古今学术的"博通"与"精专"之争、古典与现代的学术理路的差异、经世面向的缺失等问题,无论是指导思想、学术方法与研究旨趣方面,还是在传统四部之学与现代学科理论实践的融合上均有值得反思之处,应予以深切关注和彻底省察。     

Advocacy,Political Participation,and Citizenship: Lutheran Contributions to Public Theology1

Abstract : Martin Luther never developed a political theory, but his theology does inform the way Christians live in society, making it both public and political. Luther's “two kingdom theory” often has been misinterpreted to justify passivity and obedience toward civil authorities. Under closer examination, however, his theology applies to the everyday practices of politics, economics, and religious affairs. In the context of nation‐building, a Lutheran theology fosters citizenship not only as individual rights and responsibilities, but as active participation in civil society.
